ECK on AKS - Error after upgrading k8s from V1.18 to V1.19

Elastic Orchestration Elastic Cloud on Kubernetes (ECK)
1

I have installed the operator by helm:

helm install elastic-operator elastic/eck-operator -n elastic-system --create-namespace --version 1.4.0

And Elastic node by:

apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: quickstart
spec:
  version: 7.11.2
  nodeSets:
  - name: default
    count: 1
    config:
      node.store.allow_mmap: false

and I am getting below error:
